Macromatic ARP240A2 Alternating Relay for Two-Load Run-Time Balancing
Designed for duplexor control where two loads should alternate automatically, with LED indication showing which load is scheduled to energize next.
Equalize Run Time Between Two Loads
The ARP240A2 is intended for applications where two loads should share operating time instead of repeatedly favoring the same load. Its duplexor operation provides a straightforward way to alternate the connected loads as the control cycle repeats.
🔄 How the ARP240A2 Alternating Sequence Works
A control switch starts the alternating action. When the initiating switch opens, the relay output contacts change state, causing the two loads to alternate on the next cycle.
💡 LED Indication for the Next Load
Two LED indicators identify which load energizes next. This gives the operator a direct visual reference for the upcoming load in the alternating sequence.
